The largest exhibition centre in London, built on a triangular site between two Underground stations in west London

The main entrance is on Warwick Road. The main floor is given over entirely to exhibition space with a swimming pool in the centre of the ground level. The pool’s floor can be raised by a hydraulic powered ram to be used as a normal exhibiting space or an elevated stage.

The upper floor contains further exhibition space, and between the two there is a mezzanine with a series of convention halls and four restaurants from which it is possible to look down into the main area.

The building has a concrete frame with the seven main roof trusses spanning 76m each. Much of the structure is left unfinished, with concrete left as concrete and brick left as brick.

The location of the large triangular site is as good as can be found anywhere in London with Earls Court station and West Brompton situated at opposite entrances and the West London Line running the full length of the east side. The main floor is raised fifteen feet so that the basement level would not interfere with the railway tunnels.
